Drinks are no problem. 5 or 6 drops of Caproyl creating die off is indeed an extreme report and it makes me wonder if something else is going on. Perhaps it is not the Caproyl creating symptoms. Have you found a difference when you don't use it to confirm it is these five drops causing your symptoms? What are the symptoms you are associating with die off?
Of course I cannot diagnose anything but have you recently suddenly changed your diet and, if so, can you describe what you ate before and what you eat now? (A typical day).
You may wish to go through the welcome post links to help you get acquainted with some of the strategies that can help you get through the program. The links include one to a page about die off.
Taking the probiotic a couple hours away from the purge drink is fine. You can take it with or without food depending on what feels best to you.
Take care Hal,
